Fraudulent Call Alert
A recent scam has been brought to our attention in which fraudsters call clients pretending to be First Interstate or Mastercard employees asking for their PIN or social security number. Do NOT share this information with anyone. Please note, neither First Interstate nor Mastercard will ever ask for this information over the phone. For questions, please call our Client Contact Center at 1-855-342-3400.
Former INB Clients
All checks, electronic transfers, and other banking information need to be updated to First Interstate’s routing number by May 31st. The INB routing number will no longer work after this date.
